iMPROVEMENT IN REED-ORGAN VALVES.

Specification forming part of Letters Patent No. 207,907, datedSeptember 10, 1878 application filed July 8, 1876.

To all whom it may concern:

Be it known that I, HENRY W. SMITH, of West Newton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in the Val ves of Reed Organs; and do hereby declare thesame to be described in the following specification and represented inthe accompanying drawings, of which-- Figure l is a top view, and Fig. 2a side elevation, of a valve in accordance with my in vention.

It is a long valve, constructed so as to be fiexile or capable of beingreadily bent a little at and near its middle, and it is provided with abridge extending over or across the said middle or the hollow orconcavity there, and joined at or near its ends to the valve by yieldingabutments or connections, the object being to produce a long valvecapable of readily adapt ing itself to its seat when such may be more orless warped or out of place.

In constructing the said duplex valve, I make the body part A in onepiece of wood, and with a concavity, a l) c, at or near its middle, andarranged in it as shown, and form at the vertex of the concavity a slit,(1, carried transversely across the body. Across the concavity I extenda bridge or bar, 13, which I join near its ends to the parts a c of thevalve by yielding abutments or connections f f, such as pieces of softleather interposed be tween the valve and the bridge, and connected tothem by glue or cement. The bearing-surface of the valve should be facedor cushioned with strips of leather g and cloth 71 or in any otherwell-known manner.

The valve so made, when arranged on its seat, is to be forced against itby one or more springs having their free ends bearing against the backof the bridge. A fiexile valve thus constructed will readily yield andadapt itself to its seat when the latter may be warped or out of place.

My valve is not constructed in two sections, joined by a continuousstrip of packing, and to be pivoted at their outer ends and provided atthe joint with a covering-plate, all as shown in the United StatesPatent No.175,54.2. My valve is to be pivoted at one end only, andconsequently is in one piece of wood, provided with the concavity andbridge and such flexile connections to the latter as set forth;therefore,

Vhat I claim is- 1. The improved reed-organ valve, substantially asdescribed, as having its body A provided with the concavity a Z) 0,arranged in it as described, and with the brid e 13 extendin g acrossthe concavity and joined to the body by flexile or yielding abutments orconnections f f, as set forth.

2. The valve-body A, provided with the concavity a Z) c and cross-slitd, and also with the bridge B extending across the concavity and unitedto the body by yielding abutments ff, as explained.

I'IEXRY \V. SMITH.
